CHARLES W. HICKS, OF SUTI-IERLAND, FLORIDA.

SUBSOIL-PLOW.

To all whom it may concern:

Be it known that I, CHARLES W. HIoKs, a citizen of the United States, residing at Sutherland, in the county of Hillsboro and State of Florida, have invented new and useful Improvements in Subsoil-Plows, of which the following is a specification.

The present invention has reference to sub-soil plows, and particularly to plows equipped with sub-soil attachments of the gene'ral type shown and described in my prior application, filed November 18, 1910, Serial No. 593047.

It comprehends certain improvements, hereinafter specified, in the construction of the upper guide bracket, with which the shoe-carrying bar is associated, these improvements being of such a nature as to render the attachment specially applicable to the ordinary forms of goose-neck or iron-beam plow now in use, and to permit of its being fitted to plows of that character irrespective of the angle at which the plow handles are set and of the distance between said handles.

A structural embodiment of the invention is illustrated in the accompanying drawing, wherein- Figure 1 is a perspective view of the improved plow; Fig. 2 is an enlarged plan view of the upper guide bracket and the parts directly associated therewith; Fig. 3 is a vertical section taken on the line 33 of Fig. 2; and Fig. 4 is a detail perspective view of the upper guide bracket, the parts of said bracket being shown as separated from one another.

The plow shown in said vdrawing is of the conventional goose-neck type, and includes generally the curved iron beam 1, point 2, and mold board 3, these parts being of the ordinary construction, for which reason they require no extended description. The rightand left-hand handles are indicated, respectively, by the numerals 4 and 5, and these handles are connected to the plow and braced in the usual manner.

The sub-soil attachment is located between the plow handles and to the rear of the beam, as shown, its chief element being the vertical bar 6 which is formed along one edge with a series of notches 7 and carries at its lower end the shoe 8. A handle 9, or other suitable device, is provided for raising and lowering the bar, said handle being here shown as secured to the upper bar end.

Specification of Letters Patent.

Application filed January 13, 1911.

Patented Apr. 25, 1911. Serial No. 602,440.

To guide the bar during its movements, upper and lower brackets 10 and 11 are employed, the latter being substantially identical with the corresponding element shown and described in my companion application, filed of even date herewith, to which reference may be had for a complete description. No claim for the particular construction of that element is, therefore, made in the present case. The upper bracket 10 is also similar in some respects to that shown in said companion application, but it presents cer tain improvements thereover which constitute the chief features of this invention. Said bracket 10 is located between the handles, and, as shown in Figs. 2, 3 and 4, comprises three essential parts or members, namely a central member or body portion 12, and two end pieces 13 and 14. The first of these members, i. 6., the body 12, is substantially fiat, and is provided with an enlarged central portion 15 having formed thereinv the slot 16 through which the upper portion of the bar 6 passes, the front end of said slot producing the locking shoulder 17 that is designed to interchangeably engage the notches 7 in said bar. The ends of said body member overlap and rest upon the end pieces 13 and 14, and are designed for connection thereto in such a manner as to provide for an angular adjustment of the body member relative to one of the end pieces, and an endwise or longitudinal adjustment relative to the other end piece, thereby permit-ting the bracket to be attached to the handles irrespective of the angle at which the latter are set to each other and of the distance between said handles. The end pieces themselves are formed with depending flanges 18 and 19 which are bolted or otherwise secured to the adjacent faces of the plow handles, and to obtain the above-described adjustment, one of these end pieces, in the present instance, the left-hand end piece 14, is provided with a longitudinal slot 20, with which a perforation 21 in the corresponding end of the member 12 registers, while the right-hand end piece is provided with a cup 22 that fits and cooperatively engages a reversely-arranged cup 23 formed on the right-hand end of said member 12, said cups constituting a ball-andsocket joint, as will be understood. The lefthand end of member 12 is positively connected with the end piece 14 by a headed bolt 24 which passes through perforation 21 and slot 20 and is provided with a clamping nut '25, and the right-hand end of said member and the end piece 13 have a. positive connection through the medium of'a headed bolt 26 passed through perforations 27 and 28 in cups 23 and 22, the perforation 28 being necessarily larger than that in cup '23. Bolt 26 carries a headed nut 29 which fits against the curved under surface of cup 22, as shown in Fig. 3. This arrangement has the obvious eii'ect of enabling the entire length of the bracket to be increased or decreased, to suit the varying distances between the handles, and also of enabling the members 12 and 14 to ,be adjusted angularly with reference to the member '13, to adapt the bracket, to plows wherein the handles are set at anglesother than the normal, and also to different makes of plows.

The engagement of the locking shoulder '17 with the notches in the sub-soiler bar 6 is effectedautomatically, as in the earlier construct-ion, through the medium of a sprmg .30, saidspring being hereshown as secured construction and manner of mounting with the wear plate shown and described in the said companion application.

Further description of the invention is considered'unnecessary, in View of the foregoing.

I claim as my invention:
